In the compilation film 'It Came From Hollywood' (also with John Candy, Dan Ackroyd and Cheech & Chong) I do believe it is Gilda who quips over this scene from Manster, in the character of a little girl:

"He has a little eyeball on his shoulder, like a little pal"

It Came From Hollywood was cheap and easy meat, but there are some great clips in it. Well worth searching out. 'Black Belt Jones' became the stuff of legend among my friends in 1988. I think the old VHS copy still gets passed around as an offering to appease the Gods of Blaxpoitation and 70s Kung Fu.
